I have a windows enterprise server 2003, and i want to configure it as a domain controller, also I have 25 windows xp machines, then I want to know if I need to buy CALs for every windows xp machine to connect to the DOMAIN CONTROLLER?? Or I don't need to get CALs to my windows xp machines and the DC interprets the Windows XP license as a CAL??? Greetings
